Chayote, Water Chestnut and Grass Carp Tail Soup

Why people make this soup

When you or a child has been sick for a while, or has just come through surgery, the gut often feels sluggish and appetite is the first thing to disappear. This simple, clear soup is a go-to in Cantonese home cooking for exactly that moment: it is light enough for a sensitive stomach yet nourishing enough to help the body start rebuilding. The chayote brings a clean sweetness and broad nutritional value, while the water chestnuts add a gentle cooling quality to clear any leftover heat or phlegm — something that often lingers after a cold or chest infection.

Method

1. Peel the chayote and cut into thick slices.
2. Peel and rinse the water chestnuts.
3. Rinse the grass carp tail, then pan-fry it in a little oil over medium heat until lightly golden on both sides. This step reduces fishiness and adds depth to the broth.
4. Bring 2.1 L of water to a boil in a pot.
5. Add all ingredients — chayote, water chestnuts, ginger, and the fried fish tail.
6. Cook over medium-low heat for about 40 minutes.
7. Serve the soup and eat the solids together.

Nourilo’s Tips

This soup has a naturally sweet, clean flavor that children enjoy, and it supports healthy digestion as well as overall growth and brain development in kids. Water chestnuts do double duty here: beyond clearing phlegm, they are traditionally associated with dispersing swellings and nodules, so this soup is also considered appropriate for those dealing with tumors or masses. Season lightly with salt if preferred.
